Negative Plenum Concept for Cleanrooms

The insulated aluminium lined top deck seals the cleanroom and forms an airtight negative pressure return air plenum above the cleanroom ceiling. This insures leak-free ceiling performance during the life of the cleanroom. The top deck supports the cleanroom ceiling below, with air conditioning, recirculating blowers and ductwork above. Standard deck panels are built 4' wide with welded structural C-channel on 24" centers. Clear spans to 30+ feet and deck loading to over 150 psf are available. Both vertical and horizontal laminar flow cleanroom systems are available using the negative plenum concept.
